Trials
- Won more than $93 million in damages in a landslide win as counsel for Olaplex, a California-based start-up, against L’Oreal, the largest beauty company in the world. Olaplex invented a patent-protected method for protecting and repairing hair during the bleaching process. The federal jury in Delaware returned a unanimous verdict, finding that L’Oreal had willfully stolen Olaplex’s trade secrets, willfully infringed upon two Olaplex patents, and breached the parties’ NDA. L’Oreal’s claims of patent invalidity were rejected in total, and the court doubled the non-overlapping portion of the jury’s damages award and granted attorneys’ fees and costs. The court also granted a permanent injunction barring L’Oreal from selling the infringing products and restored Olaplex to its position as the sole provider of the revolutionary hair care product it invented.
